'lf'ho coirveyers l? and G may be of any desiredconstructions and we do not luy any claim on such construction butmerely show tlirn'i to show how our elevator conveyor operates inconjunction therewith.

Having described the principalparts iiivolved ifi our invention we willbrietly dei operation of same. Our maA @nire drawn over the surface ofthe field in the diret-tion indicated by arrow' in Fig.

1. The loweimost end of our elevator is adjusted by means of the bar Csso as io be in close proximity to the ground and as the machine passesforwardly the sprocket wheels l)2 are driven in the direct-ion indicated by arrow. By means of the sprocket chains D* the pinions D3 andD5, the sprocket gearfl)7 and the' bevel gearing above de scribedconnect such sprocket gearing Wit-h the main driving shaft B. By therotation of the sprocket wheel D2 the rocking shafts E are carriedaround in a circular direction and the prongs extending from the sameassume the various positions shown iii Fig. 2 of the drawings by meansof the rollers E co-acting with the cam-way C. As the prongs pass fromthe point 2 to the point-.3 they gradually change from a substantiallyverticalposition to a substantially horizontal position so as to enterthe sheaf and elevate it until the prongs reach `the oint 4. The prongsthen` pass downward y iJi a vertical position so as to allow of theshock being stripped from the prongs and to be thrown by the impetus ofthe revolving mechanism onto the table C over which it is carried bythev cross slats D. The slats D14 carry the shock or sheaf over thetable CB and throw them over the upper end thereof onto the crossconveyer F by which they are carried in the usual manner to the mainelevator G which elevates them onto the top of the load.

In a device such as we have described the sheaves or shocks are elevatedonto the load by a .minimum amount of power which machinrf at the sainetime simple in constructiiaiU/md cheap to manufacture.

What We claim as our invention is:

1. A hay loader comprising a supporting frame, supporting wheels for theframe, vertical standards on said frame, a conveyer comprising sideboards each having their upper ends pivotally supported to the upperends ofsaid standards, and having their lower ends secured to a bracketextending from the main frame, by means of a pin through one ot a seriesof holes in said bracket, so as to vary the position of said conveyer,shafts supported at each end 0f the conveyor, sprocket wheels on saidshafts, sprocket chains passing,r over said wheels, conveying meanscarried by said chains, and means for driving the upper shaft from thesupporting wheels.

2. A hay loader comprising a Supporting frame, supporting wheelstherefor, vertical standards supported on said frame, a con veyerconsisting` ot' side boards each having one end pivotally supported onthe standards, and having their lower ends secured to a bracketextending from the main frame, by means of a pin through one of a seriesof holes in said bracket, so as to Vary the posi` tion of said conveyer,an upper and a lower shaft for the conveyer, sprocket Wheels,A onf' saidshafts, chains passing over said whees, conveying meanson Said chains, atable over which the uppe;` portion of the conveying means passes, areel located at the lower end of the conveyer, prongs thereon, one endof the upper shaft passing through one of the side boards, a sprocketwheel on said exvtended end, a countershaft on the freine having asprocket Wheel thereon, a sprocket chain extending from said wheel to'the wheel on the extended end of the shaft, emi means connecting thecountershaft with one of the supporting wheels.

`3. A hay loader comprising a supporting frame, supporting wheelstherefor, stamarde on the frame, a conveyer having its up' exch o 'i gone ami hav ihr-iv im, im to bracket eienf'ing .from the mam fiume, hymeans of a pin through one of a serios of hmee in, said hraoket` so as'o vary the position of said eonveyen whereby the lower end of the@envoyer my he adjustef in reim tion to the fiume and means 'foractuating the (ifoi'n'eyer from the supporting Wheels.
